Ursus maritimus
Polar bears probably diverged from brown bear ancestors near the Arctic coast of Eurasia early in the Ice Age. They may have evolved from coastal scavengers into active hunters of seals on sea ice. The oldest known fossil (nearly 70,000 years old) is from near Kew, England, and represents a bear much larger than those currently living.
Other fossils are from Hamburg, Germany, Yamal Peninsula (the former Soviet Union), and several sites in Sweden and Denmark. The species may have been known to Paleolithic artists, for what appear to be two polar bears are depicted on a wall in the cave of Ekain, near the northern coast of Spain.
Hence, polar bears appear to have decreased in size and retreated northward since the end of the last glaciation.
Habitat
Polar bears are considered by many to be marine mammals. The name Ursus maritimus means maritime bear. Their preferred habitat is the pack ice of the Arctic Ocean. The ice edge and pressure ridges where fractures and refreezing occur provide the best hunting ground. Bears will travel as much as 1,000 km north and south, as the ice melts and freezes.
During summer bears may remain on islands or coastlines with landfast ice, drift on ice flows, or get stranded on land where they are forced to endure warm weather.
Arctodus simus
THE POLAR BEARS ANCESTOR
( short faced brown bear )
This bear seems to have been mainly a flesh-eater and was by far the most powerful land predator during the Ice Age in North America. It may have attacked bison, deer, and horses. The largest known skull of arctodus was found by a Yukon gold miner. Another fossil from southern Saskatchewan indicates that arctodus lived there more than 70,000 years ago. This species ranged the high grasslands of western North America from Alaska to Mexico, while a lighter-built species (Arctodus pristinus) with smaller teeth inhabited the more heavily wooded Atlantic coastal region. The short-faced bear became extinct some 10,000 years ago, perhaps partly because some of its large prey died out earlier, and partly because of competition with the smaller, more herbivorous brown bears that entered North America from Eurasia.
what if its some sort of Bear island ? All bears may have migrated/ evolved from this place.. ?
Just surfing for possible monsters...
